The error wasn't caused by ldconfig, it was caused during the running of
pkg-install. When the ${PREFIX}/etc/sasldb* file doesn't exist, the
pkg-install script attempts to create an empty sasldb* file with these
commands:

    echo "test" | ${PREFIX}/bin/saslpasswd2 -p -c cyrus
    ${PREFIX}/bin/saslpasswd2 -d cyrus
    chown cyrus:mail ${PREFIX}/etc/sasldb2
    chmod 640 ${PREFIX}/etc/sasldb2

The first command adds user "cyrus" with password "test" to the sasldb file,
this is what causes the error to occur due to there was no sasldb* file for
saslpasswd2 to open (these errors can be ignored).  Next it deletes the
"cyrus" user from the sasldb2 file, leaving us with a empty sasldb2 file.
Finaly, we set the correct owner, group and permisions on the sasldb2 file.

Starting with revison *_3 or *_4 of the security/cyrus-sasl2 port, it was
broken in two due to a circular dependancy was being caused by the OpenLDAP
port depending on the security/cyrus-sasl2 port and the saslauthd daemon was
being compiled to use ldap for user authentication in the
security/cyrus-sasl2 port. You now need to install the
security/cyrus-sasl2-saslauthd, if you want to use either pam or ldap for
authentication of your users.

You also need to set the pwcheck_method (sasldb or saslauthd) appropriately
for your postfix installation (${PREFIX}/lib/sasl2/Postfix.conf  (check your
postfix docs for the correct name of this file)).
